*3 10µW, φ30µm of DC light is applied to the center of each photodiode.
Under that condition, sensitivity R is shown by following formula.
R=(Vp-Vod)/5µW
*4 Light source : laser diode of λ=780nm
*5 Extreme of sensitivity is shown by following formula.
2 x (Rp1max-Rp1min)/(Rp1max+Rp1min) x 100
2 x (Rp2max-Rp2min)/(Rp2max+Rp2min) x 100
*6 Frequency sensitivity is -3dB.(reference sensitivity : value at f= 1 MHz)
*7 In addition to 10µW, φ30µm DC light, 4µWp-p AC light is applied to the center of each photodiode. BW=10kHz
